Will touch-screens ever be fingerprint-proof?

My grimy hands need the new technology fast. While the vinegar and water wipe-down does the trick, nobody likes the idea of dousing their phone in liquid. There's been a lot of rumors about the newest iPhone having fingerprint-proof screens, and I'm all for it. Obviously, it's only a matter of time before we have a sleek, unpolluted screen that matches the design of our phones and tablets.
